Chamelaucium plant named &#39;JUPITER&#39;

ABSTRACT

A new and distinct  Chamelaucium  cultivar named ‘JUPITER’ is disclosed, characterized by a large quantity of very early blooming, medium sized, red-purple colored flowers. Flowers uniquely occur in both terminal and axillary positions. The new variety is a  Chamelaucium , normally producing cut flower stems, or as a garden or container plant.

LATIN NAME OF THE GENUS AND SPECIES

Chamelaucium uncinatum

VARIETY DENOMINATION

‘JUPITER’

BACKGROUND OF THE INVENTION

The new Chamelaucium cultivar is the product of a planned breeding program conducted by the inventor, Nitzan Nir, in Kfar Hess, Israel. The objective of the breeding program was to produce new Chamelaucium varieties for ornamental commercial applications. The new variety was selected as a hybrid seedling from the breeding program at a commercial nursery in Kfar Hess, Israel.

The crossing resulting in this new variety was made during 2008. The seed parent is the variety referred to as Chamelaucium uncinatum ‘Rotemwax,’ U.S. Plant patent application Ser. No. 13/986,492. The pollen parent is the unpatented, variety referred to as Chamelaucium uncinatum ‘Early Violet’. The new variety was discovered in August of 2010 by the inventor in a group of seedlings resulting from previously mentioned crossing, in a commercial nursery in Kfar Hess, Israel.

Asexual reproduction of the new cultivar has been performed by vegetative cuttings. This was first performed at a commercial nursery in Kfar Hess, Israel in April of 2011 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘JUPITER’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘JUPITER’. These characteristics in combination distinguish ‘JUPITER’ as a new and distinct Chamelaucium cultivar:

1. Very early blooming season.

2. Unique red-purple colored flower and red flower bud.

3. Medium flower size.

4. Both terminal and axillary flowers, forming a dense spray of abundant flowers.

PARENT COMPARISON

Plants of the new cultivar ‘JUPITER’ are similar to plants of the seed parent, Chamelaucium uncinatum ‘Rotemwax’ in most horticultural characteristics, however, plants of the new cultivar ‘JUPITER’ bloom earlier, and produce flowers in both terminal and axillary positions, compared to only terminal occurring flowers of the seed parent. ‘JUPITER’ also produces slightly less flowering stems per year than the seed parent.

Plants of the new cultivar ‘JUPITER’ are similar to plants of the pollen parent; Chamelaucium uncinatum ‘Early Violet’ in most horticultural characteristics, however, plants of the new cultivar ‘JUPITER’ bloom earlier, and produce flowers in both terminal and axillary positions, compared to only terminal occurring flowers of the pollen parent. Additionally, plants of ‘JUPITER’ produce larger flowers of a lighter red-purple color than the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘JUPITER’ are comparable to the variety Chamelaucium uncinatum ‘M.B. Violet’, unpatented. The two Chamelaucium varieties are similar in most horticultural characteristics; however, the new variety ‘JUPITER’ differs in the following:

1. Flowers produced during September through November, whereas this comparator produces flowers during February through March.

2. Flowers are darker red-purple than those of ‘M.B. Violet.’

3. Flowers are produced in both terminal and axillary positions, compared to only terminal occurring flowers of this comparator.

Plants of the new cultivar ‘JUPITER’ can also be compared to the commercial variety Chamelaucium uncinatum ‘New Eden, ’ U.S. Plant patent application Ser. No. 13/987,634. These varieties are similar in most horticultural characteristics however, the new variety ‘JUPITER’ differs in the following:

-   -   1. Flowers produced during September through November, whereas         this comparator produces flowers during February through March.     -   2. Flowers are smaller, on average 1.5 cm, compared to 2.0 cm         diameter flowers from plants of ‘New Eden.’     -   3. Flowers are produced in both terminal and axillary positions,         compared to only terminal occurring flowers of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a close up of typical flowers and foliage of ‘JUPITER’ at approximately 1 year of age. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
